A lot of folks here are probably mildly annoyed by the SSL security warning that greets them each time they visit the site or refresh the page.
The SSL cert just needs to be renewed and have website admin to have a reminder on their calendar to renew it probably 1 week before the date of expiration so it doesn't bug anyone else. I was also gonna suggest using LetsEncrypt since its easier to get a free SSL cert but this site is already using it, all it needs is to be renewed.
